I just repaired a Bally MPU with major battery damage. U8 had zero pads remaining. I had to jumper quite a bit on the backside (solder side), but it is repaired. I make all my jumpers neat and laid out as organized as possible. The battery acid also dropped on to the lamp driver below. Oh joy. The lamp driver is repaired too.

You can do it. Take your time and double check traces / vias and ohm things out as you go along and when you think you are finished.

Yes, I had to pull out my higher wattage iron as well on my repair. I have a flux pen I use surface mount components. I used all over my board. Then I had to use a ton if acetone for cleaning.

Looks good.

Looks good. I have a friend that has a Haunted House that has been used in years. He wants me to come over this winter and get it running. This is good inspiration.

Looking good. More photos please!

Looks great. I'm waiting for my friend to clean up his basement so I can work on his Haunted House. I'm sure I'll have lots of questions since I'm mainly a Bally guy

Nice. I reprint my Bally cards at home on our laser printer using thick stock paper. Nothing like a set of fresh looking instructions to finish off a game!
